Foreign investment

The new age newspapers of India and the pink papers have all brainwashed us with the inevitability and inexorability of foreign investment in every sphere of economic activity. There is no ultimate terminology in the dictionary of condemnation of public spending than its inability to attract foreign investment. Well, getting some capital for an economic activity from somewhere else may surely help something to be done better but is it as necessary as it is made out to be?

A thought came to my mind that the earth as a whole has no foreign investment. No corporates from mars or venus invested in our already developed countries..Alvaa?
